Shaft transmission mechanism of motorcycle

Abstract

The invention provides a shaft transmission mechanism of a motorcycle, and belongs to the technical field of motorcycles. The shaft transmission mechanism of the motorcycle solves the technical problems that in a current shaft transmission mode of the motorcycle, after a clutch friction disc and a steering assembly are matched, the axial size, along a power input rod, of a whole formed by the clutch friction disc and the steering assembly is relatively large, and the problem exists that the structure is not compact enough. The shaft transmission mechanism of the motorcycle includes a speed changing mechanism, a transmission shaft and a driving rear axle, the transmission shaft extends along the front-rear direction of a motorcycle body, an output shaft extends along the left-right direction of the motorcycle body and penetrates through a speed changing shell, the outer end portion of the output shaft is connected with an input bevel gear in a sleeved mode, the periphery of the other end of the transmission shaft is connected with a driven shaft in a sleeved mode, the driven shaft is connected with an output bevel gear in a sleeved mode, the input bevel gear and the output bevel gear mesh with each other, a four-point contact ball bearing is arranged between the input bevel gear and the speed changing shell, the four-point contact ball bearing is sleeved on the periphery of the output shaft, and the inner end of the outer ring of the four-point contact ball bearing abuts against the speed changing shell. The shaft transmission mechanism of the motorcycle has the advantages of being less in space wasting and compact in structure.

Description

technical field [0001] The invention belongs to the technical field of motorcycles and relates to a shaft transmission mechanism of motorcycles. Background technique [0002] The rear wheel drive forms of motorcycles generally include chain drive, belt drive and shaft drive. Among them, chain drive is the most widely used form on motorcycles at present. It has the advantages of shock absorption effect, low cost and simple maintenance; belt drive is a seated The general transmission method of motorcycles, it has simple structure, low noise, soft work but weak ability to transmit torque; shaft transmission is generally used on large motorcycles, it is easy to maintain, high transmission efficiency, reliable and durable, and can be installed The reverse gear mechanism is also an advantage of the shaft drive form. [0003] The Chinese patent with the authorized notification number CN 205908715 U discloses a transmission shaft of a motorcycle gearbox, including a power input sha...

AI Technical Summary

Problems solved by technology

[0004] The above-mentioned structure provides a shaft transmission form of a motorcycle, but there are some defects: the power output by the engine is transmitted to the gearbox after passing through the steering group, and the actual engine A clutch needs to be arranged between the transmission and the gearbox to control the power intervention of the motorcycle. Under this structure, after the clutch friction plate cooperates with the steering group, the overall axial size of the power input rod is relatively large, and there is a problem that the structure is not compact enough.
